XL Drive Family Power Expansion
Higher Power Levels.
The XL VFDs can be run in
parallel to produce higher power levels than single
banks. Two, three, or four banks can be combined
to obtain the desired power. The example below
shows how an XL VFD can be expanded to four
banks for a power of 120 MVA (156,000 hp). The
table shows the maximum power levels available
from the VFD family.
The multi-bank VFDs provide drive and control
redundancy for improved reliability.
•
Synchronous or Induction motor can control
rotating machinery directly for low and high
speed applications.
•
A redundant control cabinet signifi cantly
enhances reliability.
•
Synchronous motor can control rotating
machinery directly for low and high speed
applications; paralleling reactor feeds the motor

One bank can be redundant to other three banks
for increased reliability.
